A further object of the invention is to.

l provide an auxiliary switch in said electriccircuit for opening andclosing the circuit in an open position of the main-switch.

A stillsfurther object of the inventlon 1s to lprovide an auxiliaryswitch of such a 2 character as to permit of its actuation, eitherdesignedly or accidentally, to close the electric circuit from a pointremote from the switch.

Other and more specific objects of the invention will be apparent fromthe following description and claims.

In a preferred embodiment of the present invention, an ordinary type ofalarm-clock is emploved to at a predetermined time actuate a switch tosuccessively close and open an electric-lamp circuit whereby to firstintermittently flash a light a plurality of times and thereafter.provide a constant light.

The alarm-clock is preferably sustained by an insulated base providedwith two pairs of spaced contact-members constituting the stationaryelements of main and auxiliary electric-circuit controlling switches.Projecting upwardly above the base and d1sposed between each pair of thestationary f contact-members is a guide-post for a vertically shiftabletube of some insulating ma- Vterial such as porcelain, eachtube'carrying at its lower end an electric-current conduct ing elementadapted in the lowered position ofthe tube' to bridge the stationaryconta'ctlowered or circuit-closing position. The two palrs of statlonarycontact-members are so connected with an electric-lamp circuit that teither switch may be employed to close the circuit in an open positionAof the other switch. Consequently the auxiliary switch may be employedto close the circuit to light the lamp While the clock alarm-stem is setto hold the main-switch open. The tube of the auxiliary'switch carries alateral arm which in'an open positon of said switch overlies an angularrest-rod projecting upwardly from the supporting-base. Surrounding saidlateral arm is a ring connected to a cord which may obviously bemanipulated from a point remote from the switch toclose the circuit andlight the lamp, said ring being free to slide off the lateral arm uponmanipulation of the cord.

In the-accompanying drawings, Fig. 1 is a rear elevation, with thesupporting-base in longitudinal section, of the present improvedlight-controlling,device. Fig. 2 is a top plan view of thel same, withthe alarm-clock casing partly in section. Fig. 3 is a sectional viewsubstantially on the line 1-1 of Fig. 1. Fig. 4 is a detail sectionalview of a modified supporting base and showing a diierent form ofconstruction of stationary cont-actmefmbers. Fig. 5 is a top plan viewof the modification, showing the supporting-post in section.

Referring to the drawings, a supporting base 1 of some suitableinsulating material constitutes the upper plate of a casing of anydesired form or outline, being in the present instance shown asrectangular. Preferably rigidly secured upon the base 1 is anelectric-lamp 2 having two current-lead connections, as 3 andV 4, ofwhich the current-lead 3 extends from a suitable current- Asupply sourcethrough a casing-bushing 5.

The supporting-base 1 is provided with spaced apertures, as 6 and 7underlying which is a stationary contact-member carrying plate 8 ofinsulating material secured to the under side of the base 1 by screws as9;

Secured upon the upper face ofthe plate 8 by current-transmittingscrew-bolts, as 10, are the Shanks of vstationary contact-members 11,12l and 13 bent upwardlyand partly backwardl to form spaced inclinedprojections within the apertures 6 and 7, the contact-member 12 beingcommon to both apentures. The lamp current-lead 4 is connected to thebolt of contact-member 11 which is'in evident that the descri mit atransmission of current to the lamp 2 28 surroundin turn connected bmeans of a current-lead 14 to the bolt ot contact-member 13. Thecontact-member 12 is similarly connected to a return lead 15 whichpasses through the bushing 5 to the supply source. It will be edconnections per- .17, slidingly and rotatively guiding the tubes 18 and19 of porcelain or othersuitable. material, the lower ends of whichtubes are' provided with the shiftable contactmembers 2O and 21.Adjustably clamped l .upon the tube 18 is a laterally extending arm 22havin a downwardly curved free end and whlc arm is connected by means ofa lring 23 with the offset free end of a lever 24 pivotally supportedupon the usual alarmsetting stem 25 provided on the rear face of anordinary type of alarm-clock 26. The

alarm-clock 26 is sustained by the base 1 and is preferably held clampedin operative positron by means of a. cleat 27 engaging the 'i vflangedrear end of the clock-casing.

The lever 24 is provided with a' cam-slot the alarm-winding stem 29which rotates 1n a direction reversely of the winding direction uponbeing released at a gredetermined time by the clock-mechanism. ecuredupon said stem 29' for rotation i therewith is adisk 30 carrying -aradially o'set. stud-screw 31 comprising a crankmember adapted to engagethe upper wall of the cam-slot 28. In operation, the clockalarm. iswound and set as usual, but the winding of the alarm is preferablyterminated at a point wherein the screw 31 occu- Q pies its limit ofupper movement. whereby the engagement of said screw with. the levery24-causes the shiftable contact-member 20 to raise the tube whereu 'Aas beheld in raised or switch-open position.

AtV the predetermined time, the stem 29 com- `mences to rotate causingthe lever 24 to vibrate and permitting the tube 18 to gravita.- tionallydescend to close the electric-circuit connections with the lamp 2. Inthe continued rotation of the stem 29, the tube 18 is again lifted,which o eration is repeated urality of times t ereby causing the aligiit to flash intermittently. The weight of the tube 18 is such thatas the alarm-spring becomes unwound it is finally too weak to n theactuating mechanism comes,to rest 1n switch-closed position.

The `tube 19 and its contact-member 21 comprise a shiftableswitch-member auxiliary to l,the main switch 2O and has for its primefunction to provide for closing the -the raised or switch-openllamp-circuit in the open position of the switch 20, so that the lightof the lamp 2 may be employed to set the device for operating theswitch-element 20. The tube 19 adjustably carries alateral arm 32 whichin osition of said tube may be caused to overlie the horizontal portion33 of a bent rest-rod 34 suitably secured upon the-base 1. In order toprovide for releasingthe arm 32 from the rod 34 from a point remote fromthe device, the arm 32 is loosely surrounded by a ring 35 connected to acord 36. The cord 36 may also, if desired, be so positioned as to causedetection of an unauthorized intrusion upon the premises, as willibeself-evident.

In Figs. 4 and 5 is shown a modified form of 'constructiomfor thestationary contactmembers. A supporting base 37 is dished on its undersurface and 'is provided on its upper side with a circular recess 38which at diametrically opposite points merges into small segmentalrecesses, as 39 in each of which is dispo:ed a portlon of a rounded head4() of a bolt 41 suitably secured upon the base 37 to connect current.leads therewith. The bolt-heads 40 in this instance constitute a pair-of spaced stationary contact-members adapted to be bridged by a movablecontact-member guided by a post 42 also secured upon the base 37medially of said bolt-heads.
